Steps to reproduce:
1. Start non-elevated TC (I use 32-bit one under Windows 7x64).
2. Create a folder TEST and put some junction into it.
3. Edit folder permissions: disable inheritance, set read and execute for current user and full access for administrators.
4. Try to delete folder. TC warns about non-empty folder, confirm.
5. TC reports an error during deletion, try to repeat some times, no luck. No elevation is requested.
6. Create some empty subfolder in TEST folder and try to delete TEST folder again.
7. TC warns about non-empty folder, confirm. TC shows error dialog for created subfolder with skip-retry-ignore-elevate-cancel buttons. Press either As administrator or All as administrator, no matter.
8. TC have deleted empty folder but couldn't delete junction, so situation repeats from step 5.
